    On the moon, there’s no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. Technically, it’s considered an exosphere.

    In an exosphere, the gases are so spread out that they rarely collide with…[Read more]

    T8: If an aircraft can do it, then a rocket can too.

     

    The pressure at about 35,000 ft. is about 3.47 psia (psi absolute) or 3.7 lbs. per square inch. The pressure at 60,000 ft. is only 1.05 psia. The pressure at 100,000 is 0.162 psia. The pressure at 150,000 is 2.1 x 10-3 psia! See the trend?

    An aircraft would collapse at the higher…[Read more]

    T8: That the difference between an inflated car tyre and sea level is about double.

     

    That would be true.

     

    T8: Likewise, the difference between space and a region of the atmosphere with 2 molecules is double.

     

    A cubic meter only having 2 molecules in it would be better described as “space” rather than an atmosphere. Remember that our…[Read more]

    By the way, I looked up the thickness of the walls on the lunar lander and basically it was about the thickness of a coke can, about  0.3 mm. But they brought a roll of duct…[Read more]

    It looks like you are saying that to hold pressure the container must be robust!

    I wonder how a few sheets of aluminum foil would hold up?

    It looks like we are all learning about vacuums – and it doesn’t suck.

  • Dig4truth replied to the topic Flat Earth? in the forum View Points 3 days, 8 hours ago

    From what I understand that would be an absolute vacuum. What the important thing is the way it is expressed in scientific terms. For instance;

    Vacuum gauge is measured from ambient air pressure in the negative direction. So for example at ambient air pressure the vacuum reading is 0 bar gauge and if a suction pressure of 0.25 bar is applied, the…[Read more]

    T8: By that reasoning, how much is the difference between sea level and a car tyre? Probably the same or even more?

     

    Between sea level (not sea curve) and a car tire would approximately be twice the pressure. But then you’re only going from 14.7 to 35 psi.

    Not the same with a vacuum. A vacuum is not just 0 psi. A vacuum is less than 0 psi. I…[Read more]

    At sea level on Earth, we breathe in an atmosphere where each cubic centimeter contains 10,000,000,000,000,000,000 molecules; by comparison the lunar atmosphere has less than 1,000,000 molecules in the same volume.

    So, by NASA’s website the moon’s atmosphere is 10,000,000,000,…[Read more]

    Here is an important point, even if the math is off by a factor of 10 to 100 it would still have the same result because of the immense pressure differential!

  • Dig4truth replied to the topic Flat Earth? in the forum View Points 1 week, 2 days ago

    I had to look at all kinds of conversion tables to get a grip on this but when it clicks it is astounding! If I had to take a stab in the dark at the tire pressure it would be around 32,000,000 psi and of course the outside would still be 14.7 psi. Wow, talk about over-inflating!

    Shall we consider the astronaut’s suits on the moon…[Read more]

    The thermosphere is the layer in the Earth’s atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions in the ionosphere. Taking its name from the Greek θερμός (pronounced thermos) meaning heat, the therm…[Read more]

    At Sea level the pressure is 1,013.25 millibars.

    Near Earth’s surface the pressure decreases with height at a rate of about 3.5 millibars for every 30 metres (100 feet). However, over cold air the decrease in pressure can be much steeper because its density is greater than warmer air. The pressure at 270,000 metres (10−6 mb) (167.7 miles) is com…[Read more]

    Mike, that will be an important video! In my opinion that is one of the most glaring pieces of evidence that they have no answer for. I can’t tell you how many people I have spoken to that when this is brought up they either just shut down or more likely dismiss it and continue on with other points. I would love to have a concise video I can…[Read more]

    Awesome Mike! With age comes wisdom – sometimes! I’ll be praying that the weather will be spectacular for the event.

    Eyes wide open.

    Mike, I’ve been keeping up with the progress! Can’t wait to see the results. I particularly liked the short little promo video that was done for this event!

    The sun rose and set in a little over 12 1/2 hours in Oban. I’m not familiar with the places in NZ but I think that is in the south.

    For anyone following the “vacuum” debate I would highly recommend watching this very short video!

    What NASA admits doesn’t make any scientific sense!

    Thanks Ed. I like the way you phrased that. The path of the “Sun”.

    I was wondering if you talking about the seeing the actual sun or just the light from it while it’s on the path.

  • Dig4truth replied to the topic Flat Earth? in the forum View Points 3 weeks, 4 days ago

    Ed, could you explain what you mean by (sun-cycle)?
